Description

Fine dust blocking mask with convenient breathing {MASK FOR FILTERING OF FINE DUST HAVING EASY BREATH}

The present invention relates to a mask for blocking fine dust with convenient breathing.

In general, yellow dust is fine dust originating from regions such as China and Mongolia, and mainly consists of soil components such as silicon, iron, manganese, and aluminum. As the same harmful chemicals are contained in large quantities, the harm and severity thereof are increasing day by day.

The typical concentration of heavy metals contained in yellow dust is 2 to 15 times higher than that of general air, and lead is 13 times, cadmium is 14 times, and chromium is 21 times higher. Lead paralyzes nerves and muscles, and cadmium causes lung cancer. Chromium is known to increase the risk of kidney disease and bronchitis.

In addition, the ultrafine dust included in yellow dust has a more serious adverse effect on the human body, passing through the respiratory barriers such as the nose and bronchi and accumulating in the lungs, or directly penetrating blood vessels as well as the kidneys and liver, and patients with chronic obstructive respiratory disease (COPD) whose alveoli are damaged. ) or asthmatic patients.

According to a recently published paper, ultra-fine dust of 0.1㎛ or less enters blood vessels directly through blood vessels and clots blood, interfering with blood circulation. It is known that it increases by 24%, and the probability of dying from cardiovascular disease also increases by 76%.

Various masks have been proposed as a way to solve the above problems.

Representative of such a mask is Republic of Korea Utility Model Registration No. 20-0282997, antibacterial mask (registration date: July 10, 2002). As shown in FIG. 1, the antibacterial mask has a HEPA filter, which is an antibacterial filter used in air conditioners, inserted between the outer shells. was folded several times to make the surface area more than 1.5 times larger than the outer skin.

The above-mentioned conventional mask can improve the function of filtering fine dust by having a HEPA filter built in between two layers of outer skin, but since the mask has a multi-layer structure consisting of two layers of outer skin and a HEPA filter folded several times, It is difficult to inhale and it is difficult to discharge the internal air to the outside, so it is difficult to breathe.

In addition, the above-described conventional mask has a disadvantage in that it cannot easily filter fine heavy metal dust such as lead and cadmium included in recent yellow dust. In addition, since the conventional mask cannot remove ultra-fine dust of 0.1 μm or less, there is a limitation in preventing cardiovascular diseases, which have recently been seriously emerging.

Hereinafter, a preferred embodiment of the present invention will be described in detail based on the accompanying drawings FIGS. 2 to 13, and the same reference numerals are given to the same components in FIGS. 2 to 13. On the other hand, in each drawing, the illustration and detailed description of the configuration and its action and effect, which can be easily known by those skilled in the art from general technology, are simplified or omitted, and the parts related to the present invention are mainly shown.

In addition, in most of the accompanying drawings in order to explain the embodiments according to the present invention, only the conductive wire (d) composed of the discharge electrode 22 is markedly exaggerated and the illustration of the fiber thread is omitted, but this does not improve the understanding of the invention. It is simplified and emphasized to help, and the fiber yarn is also supplied with weft and warp yarns and intertwined with each other. In addition, since the mask pad 1 is formed in the form of a fabric, the thickness is actually thin, but in the accompanying drawings, the thickness is exaggeratedly thick for better understanding.

2 is a perspective view showing a mask for blocking fine dust with convenient breathing according to a first embodiment of the present invention, and FIGS. 3a and 3b are discharge electrodes or accelerators of the mask for blocking fine dust with convenient breathing according to the first embodiment. It is an enlarged perspective view of parts A and B in FIG. 2 as a drawing showing examples of conductive wires that can be used as electrodes.

Referring to FIG. 2, the mask for blocking fine dust, which is convenient for breathing according to the first embodiment of the present invention, has a mask pad (1) through which air is introduced and discharged, and fine dust introduced into the mask pad (1). It includes an electrostatic generator 2 that filters out.

The mask pad 1 is a pad-shaped member that covers and protects the nose or mouth, and is formed of woven paper or non-woven fabric, which is widely used as a material for mask pads. In addition, the mask pad 1 can be formed in various shapes such as a rectangle, a hemisphere, an ellipse, etc. using various woven papers proposed to effectively filter fine dust. However, in the accompanying drawings, the mask pad is rectangular. Describe what has been formed.

In addition, the mask for removing fine dust includes a pad fixing member 3 formed of a string or an elastic band to maintain the mask pad 1 in a seated state. The pad fixing member 3 may also be configured with a band having a Velcro fastener, a band having a binding ring, or the like.

In addition, the mask pad 1 is woven into woven paper by supplying fiber yarn to a loom as weft and warp yarn (here, weaving is a concept including weaving and knitting), but as will be described later, the discharge electrode 22 and the accelerating electrode ( 23) is supplied as a part of the weft or warp during weaving of the fabric paper, and is woven together.

Also, the mask pad 1 may be made of non-woven fabric. In this case, the conductive wire (d) may be configured by attaching to the surface of the non-woven fabric, embroidering and arranging in the embroidery method, or embedding and arranging the inside of the non-woven fabric, and illustration thereof is omitted in the drawing.

On the other hand, the weft and warp yarns used for weaving the mask pad 1 induce static electricity even when the static generator 2 is not operating, such as polyolefin fiber yarns that easily generate static electricity themselves so that they can filter out fine dust. It is preferable to apply fibrous yarn.

In addition, the weft and warp yarns (not shown) may be selected and applied to the outside of the core part formed of a plurality of filament yarns to improve the filtration efficiency or dust collection efficiency of fine dust.

In addition, the weft and warp yarns are preferably woven by selecting fiber yarns called microfibers or ultramicrofibers that have excellent filtering efficiency or dust collection efficiency of fine dust. Here, the microfiber is a fiber yarn having a fineness (thickness) of 0.5 to 0.05 denier.

4A is a schematic block diagram showing an example of an electrostatic generator applicable to a mask for blocking fine dust with convenient breathing according to a first embodiment of the present invention, and FIG. 4B is a schematic block diagram of the first embodiment of the present invention. A schematic block diagram showing another example of an electrostatic generator that can be applied to a mask for removing fine dust with smooth breathing according to FIG. 4C is a mask for blocking fine dust with convenient breathing according to the first embodiment of the present invention. It is an exploded perspective view showing the applicable static electricity generation module.

Referring to FIGS. 2 to 4C, the static electricity generating device 2 includes a static electricity generating module 21 that generates a static electricity generating potential, and a discharge electrode 22 to which the static electricity generating potential generated from the static electricity generating module 21 is applied. to provide

Here, in the electrostatic generator 1 according to the present invention, when the mask pad 1 is formed of synthetic fiber yarn such as polyolefin, which is a material that is charged when an electrostatic field is applied, the mask pad 1 functions as a charge body. Even if only the static electricity generation module 21 and the discharge electrode 22 are provided, static electricity is generated and fine dust can be removed. An electrode 23 is further provided.

The discharge electrode 22 is disposed inside the mask pad 1 and is composed of a conductive line (d) capable of conducting current.

In addition, the discharge electrode 21 has a static electricity generation potential (ie, high-voltage (negative) The static electricity generation potential of negative (-) potential is applied from the static electricity generating module 21 so that a potential) is formed.

The accelerating electrode 23 is disposed on the outside of the mask pad 1 to face the discharge electrode 22, and the negative (-) potential of the discharging electrode 22 prevents fine dust from accelerating the electrode 23. A low-voltage positive (+) potential (i.e., base potential) is applied from the static electricity generating module 21 in order to be quickly and effectively adsorbed. In other words, in the process of forming an electrostatic field by applying a negative (-) potential from the discharge electrode 22 to the accelerating electrode 23, a low-voltage positive (+) potential is applied so that the dust collecting area is more strongly charged with a negative potential. It performs the function of accelerating the polarized fine dust to be adsorbed more quickly. That is, the accelerator electrode 23 can remove fine dust even if only the discharge electrode 22 is provided in the electrostatic generator 2, but is added for more rapid and effective removal.

Also, the conductive lines (d) applied to the discharge electrodes 22 and the accelerating electrodes 23 are arranged to have a plurality of bent portions so as not to be broken or damaged even when a tensile force is applied to the mask pad 1 . At this time, the discharge electrode 22 is disposed on the inner surface of the mask pad, and the accelerating electrode 23 is buried inside the fiber yarn outside the mask pad. And, the bent portion is formed to have a substantially sinusoidal waveform structure.

The conductive wire (d) may be constructed using only conductive wires capable of conducting current, such as copper wires, but in this embodiment, it is supplied to a loom (not shown) as a part of weft or warp along with fiber yarn when weaving fabric paper. Since it is woven or supplied as embroidery thread to the embroidery thread supply unit of the embroidery machine (not shown) and woven into the mask pad 1, as shown in FIG. The conductive yarn d2 disposed on the outer surface of d1) and the sheath yarn d3 disposed on the outer surface of the conductive yarn d2 are sequentially wound.

The core yarn (d1) is composed of a fiber yarn to satisfy flexibility, but a fineness (thickness) in the range of 5 to 2000 denier is applied. Here, when the fineness of the core yarn (d1) is 5 denier or less, the thickness is too thin, making it difficult to wind the conductive yarn (d2) and cannot be configured to have sufficient tensile strength. It is too thick, causing an increase in the overall thickness of the conductive wire (d), and has a disadvantage in that flexibility is lowered and weavability is lowered. Here, 1 denier means the thickness when 1 gram of fiber material is spun at 9000 meters.

The conductive yarn d2 is disposed along with the central yarn d1 and is woven or wound around at least one outer surface of the central yarn d1.

The conductive thread (d2) may be a metal thread formed of a conductive metal, a carbon thread, a fiber thread containing a conductive material (conductive metal nanoparticles, metal oxide particles, graphene, etc.), a fiber thread coated with a conductive material, and the like. , It is preferable to apply a thread formed of a conductive metal thread such as copper (Cu) having relatively excellent electrical conductivity and having a diameter in the range of 10 to 500 micrometers (μm). And, the reason why the conductive metal yarn having the diameter range described above is applied as the conductive yarn (d2) is that the total diameter of the conductive wire (d) in which at least one conductive metal yarn is included is 1000 micrometers (㎛) or less. This is because it can be smoothly supplied to the loom and woven.

Conductive yarn (d2) is difficult to weave when its diameter is 500 micrometers (㎛) or more, and conductive metal yarns with a diameter of 10 micrometers (㎛ or less) are difficult to mass-produce with current production technology, making it difficult to verify quality practically. Because of this situation, in this embodiment, an insulated copper wire having a diameter in the range of 20 to 100 micrometers (μm) whose conductivity, durability and quality have been verified is applied.

The sheath yarn d3 is a line arranged to be overlaid on the outside of the conductive yarn d2, and may be arranged in a form woven on the outer surface of the conductive yarn d2, but in this embodiment, as shown in FIG. 3A, the conductive yarn d2 ) is composed of a wound structure.

And, as shown in FIG. 3B, the conductive wire (d) can be stretched against an external load such as a tensile force applied to the mask pad (1). Winded around the central yarn (d1) and the central yarn (d1) in a coil form It is possible to apply what is composed of the conductive yarn (d2) to be.

At this time, the core yarn (d1) is composed of stretchable polymer yarns called span yarns, polyurethane yarns, and the like.

Meanwhile, referring to FIGS. 4A and 4C, the static electricity generating module 21 includes a power supply unit 211, a voltage conversion control unit 212 that converts power supplied from the power supply unit 211 into a specific voltage, and a voltage conversion control unit ( 212) is provided with an electrostatic generating potential forming unit 213 that forms an electrostatic generating potential and applies it to the discharge electrode 22, and the power supply unit, the voltage conversion control unit, and the electrostatic generating potential forming unit form the case 24 is installed inside.

The power supply unit 211 may be selected and applied to at least one of a primary battery such as a line-type or coin-type battery, a secondary battery such as a rechargeable battery, and a DC power supply connected to commercial power. In FIG. 4C, the coin-type primary It is shown that the battery is built in.

The voltage conversion control unit 212 is a component that receives power from the power supply unit 211 and controls the high voltage conversion necessary for the formation of static electricity generation potential. It is a component that forms an electrostatic generation potential by high pressure and applies it to the discharge electrode 22. Here, detailed configurations of the voltage conversion control unit 212 and the static electricity generating potential forming unit 213 are the same or similar to those applied to a typical static electricity generating device, so detailed descriptions are omitted.

In addition, the static electricity generating module 21 further includes a switching unit 214 that regulates power applied from the power supply unit 211 to the voltage conversion control unit 212 . For example, the switching unit 214 is configured by installing a switch having a plurality of switching contacts in the case 24 .

In addition, the switching unit 214 may be configured to provide convenience in use by automatically operating the static electricity generating module 21 when a mask is worn and used. For example, the switching unit 214 may be composed of piezoelectric devices (not shown, piezo-electricity devices) installed on the mask pad to generate a switching signal in response to the displacement of the mask pad according to respiration. In this way, when the piezoelectric element is applied as a switching unit, even if the user does not separately perform an on/off operation, when breathing while wearing the mask pad, the piezoelectric element responds to the displacement of the moving mask pad to generate a switching signal. Since it is generated and applied to the voltage conversion control unit, there is an advantage in that it is automatically turned on.

The case 24 is a member in which the static electricity generating module and the power supply unit are embedded, and the switching unit 214 is installed and the first case 241 in the form of a circular cap is formed with a drawing hole through which terminals for connecting the discharge electrode and the accelerating electrode are drawn out. And, it is composed of a second case 242 in the form of a circular cap in which terminals of the power supply unit are installed.

Referring to FIG. 4B, the static electricity generating module 21 includes a power supply unit 211, a voltage conversion control unit 212, and a static electricity generation potential forming unit 213, and the power applied from the voltage conversion control unit 212 is converted into static electricity. An electrostatic elimination potential forming unit 215 is further provided to form the elimination potential and apply it to the discharge electrode 22.

The above-described electrostatic elimination potential forming unit 215 performs a function of forming an electrostatic elimination potential (i.e., positive potential) to easily remove (i.e., escape or separate) foreign matter adsorbed on the outside of the mask pad 1. do.

As shown in FIG. 4B, when the static electricity generation module 21 applies a positive (+) potential to the discharge electrode 22 by the static elimination potential forming unit 215, the mask pad portion of the dust collection area becomes positive (+) Since it is charged with potential, fine dust with positive (+) potential is separated and separated by repulsive force. According to this, even if a large amount of fine dust is adsorbed on the mask pad due to long-term use, it can be easily removed without performing a separate washing operation to remove it, so convenience in use is further improved.

On the other hand, the static electricity generating device 2 includes a power supply unit (not shown) such as a coin-type battery, a discharge electrode (not shown) connected to the (-) terminal of the power supply unit, and an accelerating electrode connected to the (+) terminal of the power supply unit. can also be configured. This type of electrostatic generator does not have components such as a voltage conversion control unit and an electrostatic generation potential forming unit, so the generation efficiency of static electricity is low, so the removal efficiency of fine dust is relatively low, but the structure is simple and can be implemented at low cost. It can be used for disposable or low-cost fine dust removal.

Meanwhile, reference numeral 19 in FIG. 2 denotes a module storage member formed on the mask pad to accommodate or combine the static electricity generating module.

Hereinafter, the action of the mask for blocking fine dust with convenient breathing according to the first embodiment of the present invention will be described.

Briefly explaining the action of the mask for blocking fine dust with convenient breathing according to the first embodiment of the present invention as described above, as shown in FIG. 2, first, the discharge electrode 22 and the acceleration electrode 23 are As a structure, the mask for removing fine dust disposed on the mask pad 1 is worn so as to seal the mouth and nose by placing the pad fixing member 3 on the ear. Then, when the user turns on the switching unit 211, the voltage conversion control unit 212 converts the power supplied from the power supply unit 211 into a high voltage and applies it to the static electricity generation potential forming unit 215, and the static electricity generation potential The forming unit forms an electrostatic generating potential so that a negative potential is applied to the discharge electrode 22 so that the outer portion of the mask pad 1 is charged to have a negative potential, and a positive potential is applied to the accelerating electrode 23.

In this state, when the user breathes, the positive (+) potential fine dust trying to pass through the mask pad (1) is adsorbed to the outer surface of the mask pad (1) charged with a negative potential, and is blocked instead of entering the inside. At this time, since a positive potential is applied to the accelerating electrode 23, the phenomenon in which the outer surface of the mask pad 1 is negatively charged is accelerated, and fine dust adsorption is performed more quickly.

The accompanying drawing, FIG. 5 is a view for explaining a first modified example of an electrostatic generator that can be applied to a mask for blocking fine dust with convenient breathing according to a first embodiment of the present invention.

Referring to FIG. 5, the mask for blocking fine dust with convenient breathing according to the first modified example of the first embodiment includes a mask pad 1 through which air is introduced and discharged, and static electricity filtering out fine dust flowing into the inside of the mask pad. Consisting of a generator 2, the static electricity generating device 2 includes a static electricity generating module 21 that generates a static electricity generating potential and a discharge electrode 22 to which the static electricity generating potential generated from the static electricity generating module is applied, An insulating sheet 5 is disposed inside the mask pad 1 in contact with the face so as not to adversely affect the human body when static electricity is generated.

Here, the insulating sheet 5 is formed by attaching a planar member formed in a mesh structure using an insulating material such as rubber-based resin to the mask pad 1 by high-frequency welding or the like.

The mask for blocking fine dust, which is convenient for breathing according to the first modified example, can fundamentally prevent adverse effects on the human body by blocking current from being conducted to the human body when static electricity is generated by the electrostatic generator 2. Normally, even if static electricity is generated, the voltage is high, but the current is minute and the energization time is very short, so the effect on the human body is insignificant.

6 is a view for explaining a second modified example of an electrostatic generator applicable to a mask for blocking fine dust with convenient breathing according to the first embodiment of the present invention.

Referring to FIG. 6, the fine dust blocking mask for convenient breathing according to the second modified example of the first embodiment includes a mask pad 1 through which air is introduced and discharged, and static electricity filtering fine dust flowing into the inside of the mask pad.

Further, the ground sheet 61 is formed in a form in which the conductive wires d are arranged in a corrugated structure on a planar member such as woven paper. Here, as the conductive line (d), the one shown in FIG. 3A or 3B may be applied. Here, non-explained numeral 611 is a ground line for discharging current leaked due to malfunction to the outside.

The mask for blocking fine dust, which is convenient for breathing according to the second modified example, can fundamentally prevent adverse effects on the human body by discharging current to the outside when static electricity is generated due to the operation of the static electricity generating device.

And, as shown in FIG. 6 of the accompanying drawings, the fine dust blocking mask, which is convenient to breathe according to the present invention, can be configured to replace only a contaminated part even if it is contaminated during use.

To this end, in the mask for removing fine dust, an auxiliary dust collecting sheet 62 for collecting dust is disposed outside the accelerating electrode 23 outside the mask pad 1.

The auxiliary dust-collecting sheet 62 may be composed of a non-woven fabric spun and formed using a polyolefin resin in which static electricity is easily generated.

In addition, the auxiliary dust collecting sheet 62 is configured to be detachable from the mask pad 1 by forming a binding means 63 such as a Velcro fastener at an edge portion. In this way, if the auxiliary dust collecting sheet 62 is provided with the binding means 63, it can be easily replaced when a large amount of fine dust is adsorbed on its outer surface.

The accompanying drawing, FIG. 7 is a view for explaining a third modified example of the electrostatic generator applicable to the mask for blocking fine dust with convenient breathing according to the first embodiment of the present invention.

Referring to FIG. 7 , in the mask for blocking fine dust, which is convenient for breathing according to the third modified example of the first embodiment, a heating wire 64 for generating heat is disposed.

The heating wire 64 is a component heated by power applied from the power supply unit, and any wire material capable of conducting power and generating heat by electrical resistance can be selected and configured without particular limitation, but in this embodiment, the mask pad 1 ) can be applied to those shown in FIGS. 3a and 3b so that they can be integrally woven when weaving.

Referring to FIG. 8, the fine dust blocking mask, which is convenient for breathing according to the fourth modified example of the first embodiment, can sterilize viruses or germs contained in the air flowing into the human body through the mask pad 1 or remove odors. The optical fiber 65 and the LED light source 66 are arranged and configured so as to be
